in Great Britain April 26, 1932 8 Claims. (01. 242-38) This invention relates'to yarn winding, doubling and like machines, and particularly to high speed machines having automatic stop motion mechanism in which the cheese being wound is withdrawn from the drum by which it is rotated, and

braked when an end breaks.

One of the objects of my present invention is to provide improved means forpreventing yarn being drawn towards the cheese being wound by the guide bowl or bowls after knock-off has taken place. A further object of my invention is to provide means for ensuring that yarn is not drawn to any appreciable extent away from the detector mechanism due to the overrunning of the cheese after knock-oif has occurred so that piecing up is facilitated. A still further object of my invention is to provide simple and efficient means for preventing damage tothe yarn by the reciprocatory guide when starting up the winding operation or 'setting on;

My invention comprises the improved combinations and arrangements of parts hereinafter described.

Referring to the accompanying sheets of explanatory drawings:-

Figure 1 is a side elevation and Figure 2 a front elevation of part of a winding frame constructed in one convenient form in accordance with this invention.

Figure 3 is a side elevation showing a modification.

The same reference letters in the different views indicate the same or. similar parts.

a indicates a cradle carrying the bobbin b be,

are enlarged detail views at A detector pulleys m and is anchored by means of a spring 11. to a stud o forming the axle of one of the pulleys m and adjustable in a long slot in the bracket 10. There is a brake q pivoted at r and resting upon a cam s pivoted to the cradle at t, the said cam 60. being supported by the adjustable stud u. When the detector arm 1 ceases to support the stop lever d, due to an end breaking, the stop lever falls and the bobbin b is lowered clear of the drum e and on to the brake q which is also moved as forward by the pivotal movement of the cam member s. v I

Connected to the stop lever d by a link or wire 0 isan arm w pivoted at w to a fixed bracket 2:. The said arm is adapted to engage an adjustable stop y upon a lever z pivoted at 2v to the bracket x. The lever z carries a yarn deflector 3. A torsion spring 3 acting on the lever 3 tends always to move the deflector 3 from the full to the dotted line position, the amount of such movement being limited by the deflector engaging a lug 10 on the bracket as. The yarn from the detector wire g passes around bowls or rollers 4, 5 and 6 and through a reciprocating guide 7. V

When the stop lever d is unsupported by the so detector arm f, the wire link 0 lowers the arm w and the deflector 3 rises to the dotted line position in Figure 1 and is held there by the lug- 10. In this' position the deflector moves the yarn clear of the path ofthe guide 7 so that it is 5 not damaged by the latter. When the stop lever d is raised in the ordinary way to start winding, the first movement of d merely takes up the gap between the arm w and the stop y on the'lever z without moving the deflector 3. It is only the last portion of the movement of d which causes the deflector to allow the yarn to come into the path of the guide 7, but the. bobbin b is then being driven by the drum e.

A second link 11 connected to the cradle a is attached to a lever 12 pivoted upon the bracket 0:. The lever 12 carries an adjustable stop in the form of a stud 13 which is adapted to engage beneath an arm 14 pivoted at 15 in the bracket :0 and carrying at its outer end the bowl or roller 5. The arm 14 when unsupported by the lever 12 rests upon 'the bracket 11:, a lug 1'7 on the arm resting on the top of the bracket. When the stop'lever d is unsupported by the detector arm f, the link wire 11 causes the lever 12 to raise the arm 14 and the bowl 5. The yarn path between the three bowls is thereby shortened, the shortening tending to compensate for the amount of yarn which may be wound upon the bobbin b after the deflector operates and before the bob- .110

bin comes to rest. By this means I ensure that piecing'up is made in the length between the detector and the front bowl 4 instead of the break being carried forward on to the back bowl 7 6 and on to the bobbin. By providing for the lost motion between the lever 12 and the arm 14, I ensure that the latter is not lifted until the bobbin has completely clearedv the drum 6 and that therefore the slackness of the yarn path does compensate for any over-run of the bobbin.

As shown in Figure 3, instead of raising the lower bowl 5, I lower the upper, bowl 6 by'a link,

and lever mechanism operatedfrom the stop lever d. It will be seen that a link or rod '20 connected to the stop lever dis coupled to a lever 21 attached by a link 22 to an arm 23 carry.- ing the rear bowl 6. The link 20 has an eye 20 therein to clear a fixed rod 24. It will be noted that as the bowl 6 is lowered it is also drawn forward so that the yarn'is moved clear of the path of the yarnguide. accomplishestheduel object of shortening the yarn path and preventing the yarn guide damaging the yarn when winding ceases;

' Several threads, each passing through its own detector wire, maybe doubled together and wound upon the bobbin or cheese I).

In the construction illustrated, each of the 25 applied thereto when knock-off occurs. The

brake material which may be leather' is held'in a socket or holder 26 secured to an extension of v a spring clip 27, each of the latter embracing and gripping a spindle 28 having a crank arm 29 at its rear end. Through said crank' arm passes arod' 30 connected at "its lower end toan extension of the stop lever 11. A spring 31 around said rod 30 rests at itslower end on a washer 32 on a shoulder on the" rod 30 and at its'upper'end, the crank arm 29 rests" thereon.

With this construction, whenknock-off'occurs,

the rod 30 is raised and tends to compress the .spring 31' against the arm-29,"re'sulting'in the turning of the spindle 28'an d the' application of 7 the brakes to the bowls "4 and 6. When the brakes are applied, the spindle 28 can turn within the spring clip, so holding thev brakes on whilst allowing the rod to have a considerable movement. When the rod 30 moves downwards, that is when the machine is set on,'the'brakes'-are released from the bowls 4 an'd 6 and the brake holders brought against the part 33 of'the bowl bowls to be braked so that individual adjustment of the brake holders to compensate for differences inv the brake pads is obviated. It'follows also that all the brakes .will be fully applied if the travel of the rodis :sufiiciently long to cause slipping between the clips or grips 27 and the spindle '28.

' The connection between the end of the stop lever d and the rod 30 may be by pin and slot 34 so that when the stop lever (the movement of which is very rapid) strikes the pin on the rod 30,

,, the latter will be forced upwards momentarily until the pin on 30 is at the top of the slot 34 duringwhich the brakes will be fully applied.

The rod 30 will then fall untilthe pin thereon is at the bottom of the slot, when the brakes will The bowl 6 therefore It will be understood theta broke my be applied to only one of the two bowls 4 and 6, preferably the back bowl 6.

In the case of the brake 36 for the lower bowl 5 (seeFigure 10), this is carried in a holder 37 upon a plate 38 pivoted at 39 (by being secured to a pin inthe turned over end of aplate 40) and havinga weight 41 connected thereto by a spring 42. When the lower bowl 5 is thrown upwards by the arm 14 as previously described, when knockoff occurs, the weight 41 will by its inertia first fail to follow the movement of 14 and will then by "cation of the brake 36 to the bowl 5. Several applications .of the brake will occur before the ,weighte comes to rest.
